Precipitation

Addition of conc. HCl to saturated Bacl₂ solution precipitates Bacl₂ ; because of the following reason : (a) It follows from Le Chatelier's principle (b) Of common-ion effect (c) Ionic product (Ba++)(cl) remains constant in a saturated solution (d) At constant temperature, the product (Ba2+)(cl-)2 remains constant in a saturated solution:

Q : Thermodynamics I) Sulphur dioxide (SO2)

I) Sulphur dioxide (SO2) with a volumetric flow rate 5000cm3/s at 1 bar and 1000C is mixed with a second SO2 stream flowing at 2500cm3/s at 2 bar and 200C. The process occurs at steady state. You may assume ideal gas behaviour. For SO2 take the heat capacity at constant pressure to be CP/R = 3.267
